Money is the Top Cause of Stress at Work

The research by Harris Interactive on behalf of Everest College found that nearly three-quarters of employed Americans are stressed out on the job.

For the second consecutive year, the research revealed that paltry paychecks were the top stressor, with 11 percent of workers ranking low wages as the most stressful aspect of job. Other parts of the job stressing employees out include annoying co-workers, commuting, unreasonable workloads and working in a job that is not their chosen career.

"Anxiety among employees reduces productivity, lessens job satisfaction, lowers morale and has a negative impact on health," Swartz said. "Workplace stress costs U.S. employers billions, and it's critical that both employer and employee take action to reduce this epidemic."

The study shows that for those without a high school diploma, low pay is the top stressor, while college graduates rate unreasonable workloads as what's keeping them up most at night.

To reduce job stress, the most critical component is working in a career of your own choosing, according to Swartz.

"If you're frustrated about your career and want to improve your situation long-term, make a plan for success," he said. "Whether you've been in a career for 20 years or are just starting out, stay current on new trends, learn practical skills and consider choosing a field of study that will translate into a job in a growth industry like health care."

Swartz points to a 2012 report from the U.S. Bureau of Labor Statistics that shows industries and occupations related to health care, personal care and social assistance, and construction are projected to have the fastest job growth between 2010 and 2020.

"All government labor projections continue to show that health care is and will continue to be one of the fastest-growing industries in the U.S.," said Swartz.

The study was based on surveys of nearly 900 U.S. full-time employees.
